'Be itl known tha-til, ARME 5G. GRDNnn,-'a

citizen of thegUnited `States,l residing at i Memphis, in thecou'nty nof VScotland andl State of Missouri,have invented certain new' and useful Improvements in VFarm-Grate Locks Vand Latches; and I do hereby declare thel following to be afull, clear and exact description of the invention,-such as will enable others skilled in the artto which it appertains to make and use the same. A

This invention relates to gate latches and the primary object of the invention is to provide an improved gate'latchhaving means for automatically locking the latching bolt against accidental movement when the gate is in its closed position.

' Another object of heinvention Vis -to provide an'improved 'gate latch having means for normally holding the latching bolt .out of operative positionV against the tension of the spring until the same is. swung closedf A further object' of the invention 1s to provide means'for releasing the latch bolt when the gate is swung to its ,closed position.'v Y Y 'A still further object of the'invention is to provide anlimproved gate latch :of the above I E character, which is dnrable andk eflicient in use', one that is simple 'and'l easyy to manufacture, and'one that" can lbe'placed uponthe market at a reasonable cost.

With'these and `other objects in `'view the invention consists in the novel construction,

arrangement and formation of parts,`as will be hereinafter more specifically described,

- AThe latch and lock l comprises metallic frame 6- having a front Ushaped section 7 and-rear vertical strips 8.! The fronty and rear sections 7Y and '8 are vbolted together `and tothe panels 5, as at 9. The strips-Bare placed directly in'- alin'ement with'v thev legs protrudes beyond the outer face ofthe gate.

The' @bolt 10 carries an out-standing headed pin 14',Y whichis fitted intheslotted end 15 ofthe The upper edge-of theU-shaped member 7 is notched tojprovideA a plurality of ratchet teeth 16, and the lever-13 has pivotal'l'yfsecured thereto a locking dog 17, v*which is adapted'to engage the teeth-16 and holdthe locking bolt jl() in. its forward "posi-tion against rearward movement; A` triangularshaped lever 18de pivotally connected tothe p `hand lever13 at one 'angle thereof by means i of a pivotv pin- 19adjacentv to the upperend lof `the U-shaped member-7 which form. a guide for thesliding latching bolt IO, which so Y thereof and 'a link 2O has the terminals f `thereof secured respectively to the triangular lever 18 and the pawl 17 adjacent to the free end thereof.- kThus itwill'be "seen that whenthev handalever' 13 is grasped and the lever 18 swung on its pivot-,the dog-17 is raised out of engagement with the ratchet teeth. v

The outer edge )flthev locking bolt `1 has vthe upper edgev `thereof notchedlto provide a l shoulder 27 and when the bolt 10 is slid rearwardly byfmeans of the hand lever 13, the same is held in` its retracted position by means of the trip lever 22, the horizontal portion 25 thereof engaging behind .the

shoulder 27 which holds the bolt against the tension of the coil spring 21. ,Thel gate post 3 is provided with an aperture 28, which constitutes a keeper for the sliding bolt 10. An outstanding pin 29 isl secured to the gate post 3 at the-outer edge of the gate post above the aperture Y28 and this pin constitutes a means for rocking the trip lever, so

as to raise-theV horizontal portion 25 thereof from engagement with the shoulder 27 so as ,Y to allow thelatchingboltl() to move outwardly under the influence of the coil spring 2l into the aperture 28, when the gate is swung closed. l

The gate swings open in one direction,

. this being toward the right in Fig. 3. After the gate has been' opened and is again closed the pin 29 engages thel upstanding end portion of the sleeve of the lever 22 and moves it out-of engagementwith the latch barlO thus releasing the latch bar so that the latch` bar may be moved by the spring 21.

1n. operation of the improvedv device, the lever 13 Vis grasped yand the triangular shaped lever 18 swung on its pivot, which raises the dog 17- out of engagement with the teeth" and the lever `13 is then operated so .as to slide the bolt rearwardly against the tension of the coil/spring and when the v same has been fully retracted, the horizontal to move forwardly under the influence of the spring 21 Yand 4into the aperture 28, which holds the gate in itsclos'ed position.

The latch is then absolutely prevented from being accidentally operated by means of the ving'v drawings vand referred to in the above description, as the preferred embodiment, is the most efficient vand practical; yet realizing` the conditions` concurrent with the changes in details, of construction, proportion and arrangement of` parts may be re-.

sorted to, when required without sacrificing any of the advantages ofv my invention as setforth."y n v What I claim as new is: N

1. A gate latch and lock comprising Aa frame, a sliding bolt carried by the frame, a lever pivoted intermediateits ends tothe frame, means koperatively connecting the lower end of the lever with the sliding bolt, a segmental rack bar mounted on the frame, a pivotedpawl carried bythe lever and arranged to engage the teeth, and means carpam or'dog 17 which holds the saine against ried by thelever for. operating thcypawl, 1

as and for the purpose s ecified.y i

' 2. The combination with a gate and` post, of-a latch therefor including a'frame, a spring pressed bolt, a shoulder formedon the forward end of the bolt, a trip lever pivoted to the gate including upwardly and downwardly extending arms and a horizontal intermediate portion normally in the path of the shoulder, la keeper secured lto' the gate po'st,and an outstanding pin .ar-

ranged above the keeper in they path vof the upwardly disposed arm. for swinging the trip on its pivot to raise the horizontal part. ofthe trip above the shoulder to permit the bolt to be projected into the keeper. v i

3. A gate latch and lock comprising a U- shaped frame having depending arms, as,

cross bar extending between and connected with the arms of the U-'sha'ped'` frame, an

cross bar and extending above. and vbelow the frame, a sliding bolt .extending transversely of the U-shaped frame and connectroo engagement with actuating lever pivotally connected with the ed with the lower end of the actuating lever, c i

the head portion of the U-shaped.I frame being cut to providev rack teeth, and means carried by the upper portion of the lever for engaging the rack teeth to releasably retain the lever in an adjusted position.

In testimony whereof Igaiix my signature in presence of twoy's'fitnesses.
